TMI8837

TMI · Motor Driver ICs · DFN-8-EP(2x2)

TMI8837 from TMI, in a DFN-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VM power_in Power supply for the driver, operating from 1.8 V to 11 V; connect a 0.1μF ceramic bypass capacitor to GND and at least 22μF bulk capacitance on VM to GND to stabilize VM during motor operation.
2 OUT1 output Motor driver output 1; absolute maximum voltage range is -0.3 V to Vin+0.3 V.
3 OUT2 output Motor driver output 2; absolute maximum voltage range is -0.3 V to Vin+0.3 V.
4 GND power_in Ground pin.
5 IN2 input PWM input 2 controlling the H-bridge per the input/output logic table; logic thresholds are referenced to VCC (VIH 0.5x to 0.6x VCC, VIL 0.25x to 0.4x VCC).
6 IN1 input PWM input 1 controlling the H-bridge per the input/output logic table; logic thresholds are referenced to VCC (VIH 0.5x to 0.6x VCC, VIL 0.25x to 0.4x VCC).
7 EN input Chip enable input; logic low puts the device into low-power sleep mode and logic high enables normal operation, with an internal pull-down resistor to GND.
8 VCC power_in Power supply for logic inputs, operating from 1.8 V to 7 V; connect a 0.1μF ceramic bypass capacitor to GND.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
